Title:
A PREPARATION METHOD OF SILICONE COMPOSITION HAVING HIGH REFRACTIVE INDEX FOR LIGHT EMITTING DIODE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/111945
Kind Code:
A3
Abstract:
The present invention relates to a method for preparing a high refractive organopolysiloxane through condensation reactions. More specifically, the present invention relates to a method for preparing a high refractive organopolysiloxane through condensation reactions using a slight amount of catalyst, by which the reduction of ion content, easy removal of silanol groups and saving of production time can be achieved simultaneously; and a silicone composition for light emitting diode (LED) devices comprising the high refractive organopolysiloxane prepared by the method.
